expand (4y-3(x-1)^2)/(z+9)

expand

\frac{4 y - 3 ( x - 1 ) ^{2}}{z + 9}

\frac{4 y - 3 x ^{2} + 6 x - 3}{z + 9}

Solution steps

\frac{4 y - 3 ( x - 1 ) ^{2}}{z + 9}

(x - 1)^{2} = x^{2} - 2 x + 1

= \frac{4 y - 3 ( x ^{2} - 2 x + 1 )}{z + 9}

Expand

4 y - 3 (x^{2} - 2 x + 1) : 4 y - 3 x^{2} + 6 x - 3

= \frac{4 y - 3 x ^{2} + 6 x - 3}{z + 9}

- 2.2 (- 12 - 5 y = - 27)

\frac{x + 1}{x ^{2}}

3 x^{2} - 6 x + 7 + 5 x^{2} + 2 x - 9

- \frac{2 ( x - 1 )}{7}

\frac{1}{x ( 4 - x )}
